Losing Playback Position

runningslow81 commented 2 years ago

When I have been listening to a book for awhile and then stop playing, when returning to the app it very frequently loses the playback position. When hitting play, it'll just restart from the beginning and not prompt me about "clearing your saved progress." I'll just wager a guess that this is related to my Plex server console reporting "Could not convert "playbackTime" ("1639074741393") to the correct type" every few seconds while I'm playing an audiobook.

Good intuition, I'd bet that's related. Thanks for sharing those logs.

That number would seem to indicate a 51 year long book. Looks like some wires might be crossed somewhere and a maybe a timestamp is getting passed in where progress ought to be?

A few questions that might make this more likely to get resolved more easily:

what version of the app are you on? (Play store, play store beta, or GitHub apk?)
Plex server version?
Does this happen with every book, or just a specific one?

And thanks for reporting the issue!

I guess that would have been important information to include!

On my primary phone, I'm currently using the GitHub apk (v0.51, but it reports as 0.45.1 on my phone?), but I saw similar behavior with the other versions, too. I also see the same behavior on another phone using the Play Store beta.
My Plex Server version is currently 1.25.2.5319 and is running in a Docker container.
It appears to happen with every single book I've tried, whether it was an m4b or mp3.

Another thing to add. I can play the same audiobooks through the Plex Web app and I don't see these playbackTime errors in the Plex Console. I'll be happy to provide more logs or any other info needed.

I am expierencing the same issue, I can share logs if needed

The playbackTime mentioned by @runningslow81 is an epoch date.

I ran it through https://www.epochconverter.com/ and the date is roughly the same time as this post was made.

I'm struggling to find proper docs for the Plex API to figure out what this value is supposed to be.

edit: I've been distracted but the web UI shows a much smaller value when playing a tv show.

I think this could be a good pointer for this issue on how to implement playback time value tracking correctly : https://github.com/Montellese/mediaimporter.plex/issues/2

Looks to be working to me now with thanks to the PR from @KevinDenis

I'm still having the issue where the app loses my playback position on apk version 0.51.1.

Since it is so intermittent, I haven't been able to watch my Plex logs when it happens. I've tried, but it never happens when I'm watching. I appear to have narrowed it down to times when (for lack of a better term) there is NOT a book "Now Playing." It would happen at times when browsing the library and pressing the play button on a book with an already established playtime. Its not every time and it doesn't happen often, but it only appears to happen in this circumstance.

I did get in the habit of recording my phone screen every time I went to restart listening and caught it happening that way.

If this worked right, this video shows normal operation of a book on the "Now Playing" screen. https://user-images.githubusercontent.com/95879270/156052896-5d6f7968-a8e0-4650-98da-38386ba8175f.mp4

This video shows the same book showing a play position of 19:28:03 and then starting at Chapter 1 when play is pressed. https://user-images.githubusercontent.com/95879270/156052910-e841cf69-1d8e-4643-a31f-13dc791c142b.mp4
